Sun on a roof in Georgetown.
The PVWatts model puts a generic roof array in Georgetown at 1,518 kWh a year for each kW of panels, using typical-year weather from a station 2.2 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against Austin
The nearest of the six largest modeled places is Austin, 41 km to the south, at 1,483 kWh per kW. Georgetown models 35 kWh per kW (2.4%) above it. Georgetown lies 0.37 degrees of latitude north of Austin, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The two weather stations sit a similar distance from their points (2.2 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is San Antonio, 156 km southwest, where the same model gives 1,505 kWh per kW, so Georgetown runs 13 above that figure. Against the Texas median place month by month, Georgetown runs at least 2% higher in January, April, August. It runs at least 2% lower in March, September, November.

Electricity prices nearby
Georgetown is served by its own municipal utility, City of Georgetown. Municipal utilities in Texas generally sit outside retail choice, so homes in the city buy from the city utility. Its 2025 residential average was 13.77¢ per kWh, which would put the modeled 1,518 kWh at $209 per kW a year, plain multiplication and not a savings estimate.
Other providers listed in the county
- Austin Energy: 13.14¢ per kWh, a bundled average, 522,446 residential customers across 2 counties.
- Pedernales Electric Coop, Inc: 12.75¢ per kWh, a bundled average, 420,753 residential customers across 24 counties.
- Bluebonnet Electric Coop, Inc: 11.59¢ per kWh, a bundled average, 119,030 residential customers across 14 counties.
- Oncor Electric Delivery Company LLC: 5.64¢ per kWh, delivery charges only, before the retail energy price, 3,545,814 residential customers across 99 counties.
These serve areas outside the city utility. They are the largest bundled providers, and the largest delivery-only one, whose EIA service territory lists the county. A county can list several, and which one serves a street depends on the address, so check your bill.

Size the array, see the kWh.
Scale the Georgetown model to another array size, take off extra losses for shade or dirt, and price the energy at any rate. It is arithmetic on the PVWatts output above, nothing more: not a quote, not a savings estimate and not advice.
Starting rate: the Texas residential average of 15.47¢ per kWh. At that rate the modeled output is worth $235 per kW a year as plain multiplication.

Getting a measured number
A model cannot see your roof. Installers measure pitch, shade and the electrical panel on site. Quote marketplaces such as EnergySage, SolarReviews and WattBuy collect bids from local installers. Rate & Roof does not rank installers.

The sliders above price the energy at one rate. The payback calculator adds the system cost and your buyback plan type, and shows every assumption. It is an estimate, not advice.
